Subject: [PATCH] scsi: myrs: only build on little-endian platforms
Date: Fri, 2 Nov 2018 16:47:23 +0100 [thread overview]
Message-ID: <20181102154740.2011289-1-arnd@arndb.de> (raw)
Reading throught the new driver, I noticed that this cannot work on
big-endian CPUs, and the old DAC960 had exactly the same behavior.
To document this for the future, add a Kconfig dependency that prevents it
from being included in big-endian kernels. Since the hardware is really
old and we never had a working driver on it for big-endian platforms,
it's unlikely to make a difference to users.
